BW Extractors for NON-BW Data Warehouse

Hi,

I am working on a client who wishes to use a custom developed Data Warehouse. Is there any way to use SAP's standard extractors to extract data to these non-sap dw systems (or download the data in flat file format from extractor after run)? We are looking for mainly LO Cockpit and Finance extractors.

Best regards,

Nikhil
